Estimated time:
45 min-hour, however, the pumpkin version may improve if the cookie/cake part is given
a chance to "mellow" overnight.

Number of servings:
16-18

Ingredients: (Hit your return key to start a new line)
Filling:

1/2 cup marshmallow fluff
1/2 cup shortening
up to 1/3 cup milk
3/4 - 1 1/2 cups powdered sugar
1 tsp. vanilla


Whoopie Pies:

2 eggs
1/2 cup vegetable oil
1 1/4 cups brown sugar
1 tsp. vanilla
3/4 tsp. pumpkin pie spice (or 1/4 tsp. each of: cloves, cinnamon, and nutmeg)
1/4 tsp. ginger
1 1/3 cup pumpkin
2 cups flour
3/4 tsp. baking powder
3/4 tsp. baking soda

Directions:
Combine Filling ingredients and whup/beat into submission by hand w/whisk, or w/electric mixer (my preference!) Refrigerate in covered bowl until ready to assemble cookies.

Combine eggs, oil, brown sugar, vanilla, spices, and pumpkin, until thoroughly blended.

Combine remaining dry ingredients; add to pumpkin mixture, beating until smooth.

Drop by well rounded Tablespoons
onto ungreased or lightly greased cookie sheet. (Half an ice cream scooperful is good.) Bake for 6-8 minutes, until the cookies have spread some and risen up nicely, with a few bubbles and/or a bit of "cracking" on top to indicate they are done thru and thru. Cool cookies and remove from baking sheet.

When cookies are completely cooled, and perhaps "mellowed" a bit, plop some Filling on one cookie, and push another cookie on top of the filling (the Oreo principle), to make a sandwich cookie, The Whoopie Pie. Finish (and finish off?) other cookies, two by two.

Don't let these sit around at room temperature for days; call your friends together, make tea, call the kids---eat them!

Other suggestions and comments:
When I made these tonight, I thought they were OK, but I'm fairly sure kids will prefer Chocolate by a wide margin (gee, I have a Wide Margin...).

The amount of powdered sugar used probably affects the Consistency more than the flavor of the filling. Play with the liquid/sugar ratios a little there. It's always easier to add more of Anything later than to remove a substance.

The spice flavoring didn't come out strong; it may taste more flavorful next day, as is often the case w/pumpkin baked goods, or the spices could be tinkered with. It's just another Whoopie Pie option, fer shur. I'd bake the Pumpkin type a day ahead, or even freeze them; the earlier Chocolate version is closer to Instant Gratification.
